Pink is good for your health
The antioxidant that triggers the red colouring in cooked prawns, astaxanthin, also plays an important role in protecting human cells from damage.
Astaxanthin, the pink in prawns and salmon prevents the initiation of cancer cells in the tongue, oral cavity, large bowel, bladder, uterus, and breast. The astaxanthin in fish is of whatever stereoisomer the fish ingested.
[Stereoisomers are isomeric molecules whose atomic connectivity is the same but whose atomic arrangement in space is different. Enantiomers are two stereoisomers that are related to each other by a reflection: they are mirror images of each other, which are non-superimposable. Human hands are a macroscopic example of stereoisomerism.]
Astaxanthin, unlike some carotenoids, does not convert to Vitamin A (retinol) in the human body. Too much Vitamin A is toxic for a human, but astaxanthin is not. However, it is a powerful antioxidant; it is 10 times more capable than other carotenoids.
Astaxanthin has a peculiar chemical structure. Astaxanthin enhances the cellular membranes stability as it locates crosswise inside them. Astaxanthin is one of those important carotenoids and might be beneficial for nerve damage associated with age-related macular degeneration.
So next time you shop head for the fish counter pick up some prawns and a seafood dip or salmon for a meal that will improve your health.
